Bug ID: 462415
Summary: Object-like and function-like macros are mixed up when
whitespace is unusual
Classification: Applications
Product: kdevelop
Version: 5.9.220803
Platform: Other
OS: Linux
Status: REPORTED
Severity: minor

Reproduction examples
SUMMARY
If a macro is defined like this:
#define SOME_MACRO (1 << 6)
it is an object-like macro due to the whitespace between macro name and the
opening parenthesis. But when that whitespace contains no ASCII space
characters (e.g. consists of a tab as in this example), KDevelop treats it as a
function-like macro.
Conversely, when in a function-like macro definition the parameter list is not
followed by an ASCII space, the macro is treated as object-like. See the
attachment for examples.
STEPS TO REPRODUCE
1. Open KDevelop
2. Open the attached file
OBSERVED RESULT
OBJ1 and OBJ2:
* are highlighted as function-like macros
* in the tooltip or the code browser,
- are described as “Function macro”
- in some cases, the replacement list is shown after the name as if it was a
parameter list
- the body may be shown as empty, or the whole line (including #define) may
be shown as the body
FUN1, FUN2, and FUN3:
* are highlighted as object-like macros
* in the tooltip or the code browser
- are described as “Macro”
- no parameter list is shown after macro name
EXPECTED RESULT
OBJ1 and OBJ2:
* are highlighted as object-like macros
* In the tooltip or the code browser,
- described as simply “Macro”
- the replacement list is shown as the body
FUN1, FUN2, and FUN3:
* are highlighted as function-like macros
* In the tooltip or the code browser,
- described as “Function macro”
- the parameter list is shown after macro name
- the replacement list is shown as the body
